Running `docker stack services <STACK> --orchestrator swarm would yield
the message "Noting found in stack: asdf" with an exit code 0. The same
command with kubernetes orchestrator would yield "nothing found in
stack: adsf" (note the lower-case "nothing") and a non-zero exit code.
This change makes the `stack services` command uniform for both
orchestrators. The logic of getting and printing services is split to
reuse the same formatting code.

API v1.41 adds a new option to get the number of desired
and running tasks when listing services. This patch enables
this functionality, and provides a fallback mechanism when
the ServiceStatus is not available, which would be when
using an older API version.
Now that the swarm.Service struct captures this information,
the `ListInfo` type is no longer needed, so it is removed,
and the related list- and formatting functions have been
modified accordingly.
To reduce repetition, sorting the services has been moved
to the formatter. This is a slight change in behavior, but
all calls to the formatter performed this sort first, so
the change will not lead to user-facing changes.

This is less of a layering violation and removes some ugly hardcoded
`"kubernetes"` strings which were needed to avoid an import loop.
Signed-off-by: Ian Campbell <ijc@docker.com>
This removes the need for the core context code to import
`github.com/docker/cli/cli/context/kubernetes` which in turn reduces the
transitive import tree in this file to not pull in all of Kubernetes.
Note that this means that any calling code which is interested in the
kubernetes endpoint must import `github.com/docker/cli/cli/context/kubernetes`
itself somewhere in order to trigger the dynamic registration. In practice
anything which is interested in Kubernetes must import that package (e.g.
`./cli/command/context.list` does for the `EndpointFromContext` function) to do
anything useful, so this restriction is not too onerous.
As a special case a small amount of Kubernetes related logic remains in
`ResolveDefaultContext` to handle error handling when the stack orchestrator
includes Kubernetes. In order to avoid a circular import loop this hardcodes
the kube endpoint name.
Similarly to avoid an import loop the existing `TestDefaultContextInitializer`
cannot continue to unit test for the Kubernetes case, so that aspect of the
test is carved off into a very similar test in the kubernetes context package.
Lastly, note that the kubernetes endpoint is now modifiable via
`WithContextEndpointType`.

Signed-off-by: Ian Campbell <ijc@docker.com>
Previously an endpoint registered using `RegisterDefaultStoreEndpoints` would
not be taken into consideration by `resolveDefaultContext` and so could not
provide any details.
Resolve this by passing a `store.Config` to `resolveDefaultContext` and using
it to iterate over all registered endpoints. Any endpoint can ensure that their
type implements the new `EndpointDefaultResolver` in order to provide a default.
The Docker and Kubernetes endpoints are special cased, shortly the Kubernetes
one will be refactored to be dynamically registered.

The comment on `github.com/docker/cli/kubernetes.NewKubernetesConfig` said:
// Deprecated: Use github.com/docker/compose-on-kubernetes/api.NewKubernetesConfig instead
By making this switch in `github.com/docker/cli/context/kubernetes/load.go` we
break a vendoring chain:
`github.com/docker/cli/cli/command`
→ `vendor/github.com/docker/cli/cli/context/kubernetes/load.go`
→ `vendor/github.com/docker/cli/kubernetes`
→ `github.com/docker/compose-on-kubernetes/api/compose/...`
This means that projects which just want `github.com/docker/cli/cli/command`
(which is itself pulled in transitively by
`github.com/docker/cli/cli-plugins/plugin`) which do not themselves need the
compose-on-kubernetes API avoid a huge pile of transitive dependencies.

This refactors the way networking options are parsed, and makes the

For backward-compatibility, the following global networking-related
options are associated with the first network (in case multiple
networks are set);
- `--ip`
- `--ip6`
- `--link`
- `--link-local-ip`
- `--network-alias`
Not all of these options are supported yet in the advanced notation,
but for options that are supported, setting both the per-network option
and the global option will produce a "conflicting options" error.

This adds validation to `docker container run` / `docker container create`;
Validation of labels provided through flags was removed in 31dc5c0a9a,
after the validation was changed to fix labels without values, and to prevent
labels from being expanded with environment variables in 2b17f4c8a8
However, now empty label names from _files_ (`--label-file`) followed different

This patch fixes a bug where labels use the same behavior as `--env`, resulting
in a value to be copied from environment variables with the same name as the
label if no value is set (i.e. a simple key, no `=` sign, no value).
An earlier pull request addressed similar cases for `docker run`;
2b17f4c8a8, but this did not address the
same situation for (e.g.) `docker service create`.
Digging in history for this bug, I found that use of the `ValidateEnv`
function for labels was added in the original implementation of the labels feature in
abb5e9a077 (diff-ae476143d40e21ac0918630f7365ed3cR34)
However, the design never intended it to expand environment variables,
and use of this function was either due to either a "copy/paste" of the
equivalent `--env` flags, or a misunderstanding (the name `ValidateEnv` does
not communicate that it also expands environment variables), and the existing
`ValidateLabel` was designed for _engine_ labels (which required a value to
be set).
Following the initial implementation, other parts of the code followed
the same (incorrect) approach, therefore leading the bug to be introduced
in services as well.
This patch:
- updates the `ValidateLabel` to match the expected validation
rules (this function is no longer used since 31dc5c0a9a),
and the daemon has its own implementation)
- corrects various locations in the code where `ValidateEnv` was used instead of `ValidateLabel`.
Before this patch:
```bash
export SOME_ENV_VAR=I_AM_SOME_ENV_VAR
docker service create --label SOME_ENV_VAR --tty --name test busybox
docker service inspect --format '{{json .Spec.Labels}}' test
{"SOME_ENV_VAR":"I_AM_SOME_ENV_VAR"}
```
After this patch:
```bash
export SOME_ENV_VAR=I_AM_SOME_ENV_VAR
docker service create --label SOME_ENV_VAR --tty --name test busybox
docker container inspect --format '{{json .Config.Labels}}' test
{"SOME_ENV_VAR":""}

The warning, printed before running `docker system prune` was printing the
filters in JSON format.
This patch attempts to make the output human readable;
- updating the code, and template to print filters individually
- reducing the indentation (which was quite deep)
Before this patch was applied;
```
docker system prune --filter until=24h --filter label=hello-world --filter label!=foo=bar --filter label=bar=baz
WARNING! This will remove:
- all stopped containers
- all networks not used by at least one container
- all dangling images
- all dangling build cache
- Elements to be pruned will be filtered with:
- label={"label":{"bar=baz":true,"hello-world":true},"label!":{"foo=bar":true},"until":{"24h":true}}
Are you sure you want to continue? [y/N]
```
With this patch applied;

The warning, printed before runing docker system prune was missing any filter
that was set in the configuration file. In addition, the warning prefixes the
filters with `label=`, which is no longer accurate, now that the prune command
also supports "until" as a filter.
Before this change, only the filters set on the command-line were shown,
and any filter set in the configuration file was missing;
```
mkdir -p ./test-config
echo '{"pruneFilters": ["label!=never=remove-me", "label=remove=me"]}' > test-config/config.json
docker --config=./test-config system prune --filter until=24h --filter label=hello-world --filter label!=foo=bar --filter label=bar=baz
WARNING! This will remove:
- all stopped containers
- all networks not used by at least one container
- all dangling images
- all dangling build cache
- Elements to be pruned will be filtered with:
- label={"label":{"bar=baz":true,"hello-world":true},"label!":{"foo=bar":true},"until":{"24h":true}}
Are you sure you want to continue? [y/N]
```
With this patch applied, both options from the commandline and options set
in the configuration file are shown;
```
mkdir -p ./test-config
echo '{"pruneFilters": ["label!=never=remove-me", "label=remove=me"]}' > test-config/config.json
docker --config=./test-config system prune --filter until=24h --filter label=hello-world --filter label!=foo=bar --filter label=bar=baz
WARNING! This will remove:

This happens on Windows when dialing a named pipe (a path which is used by CLI
plugins), in that case some debugging shows:
DEBU[0000] conn is a *winio.win32MessageBytePipe
DEBU[0000] conn is a halfReadCloser: false
DEBU[0000] conn is a halfWriteCloser: true
the raw stream connection does not implement halfCloser
In such cases we can simply wrap with a nop function since closing for read
isn't too critical.
Signed-off-by: Ian Campbell <ijc@docker.com>
The `conn` here is `*winio.win32MessageBytePipe` which does not have a
`CloseRead` method (it does have `CloseWrite`) resulting in:
docker@WIN-NUC0 C:\Users\docker>.\docker-windows-amd64.exe system dial-stdio
the raw stream connection does not implement halfCloser
Also disable the path which uses this for cli-plugins on Windows.

This means that plugins can use whatever methods the monolithic CLI supports,
which is good for consistency.
This relies on `os.Args[0]` being something which can be executed again to
reach the same binary, since it is propagated (via an envvar) to the plugin for
this purpose. This essentially requires that the current working directory and
path are not modified by the monolithic CLI before it launches the plugin nor
by the plugin before it initializes the client. This should be the case.
Previously the fake apiclient used by `TestExperimentalCLI` was not being used,
since `cli.Initialize` was unconditionally overwriting it with a real one
(talking to a real daemon during unit testing, it seems). This wasn't expected
nor desirable and no longer happens with the new arrangements, exposing the
fact that no `pingFunc` is provided, leading to a panic. Add a `pingFunc` to
the fake client to avoid this.

Fairly straight forward. It became necessary to wrap `Plugin.Err` with a type
which implements `encoding.MarshalText` in order to have that field rendered
properly in the `docker info -f '{{json}}'` output.
Since I changed the type somewhat I also added a unit test for `formatInfo`.

This helps to avoid circular includes, by separating the pure data out from the
actual functionality in the cli subpackage, allowing other code which is
imported to access the data.

All of the current callers follow the pattern:
dockerPreRun(opts)
err := dockerCli.Initialize(opts) ...
So there is no semantic change into merging the content of `dockerPreRun` into the head of `Initialize`.
I'm about to add a new caller outside of the `cmd/docker` package and this
seems preferable exporting `DockerPreRun`.

This will allow plugins to have custom typed endpoints, as well as
create/remove/update contexts with the exact same results as the main
CLI (thinking of things like `docker ee login https://my-ucp-server

That is, reindent the two sections by one space.
While the code was done by hand the `.golden` files had the extra space
inserted with emacs' `string-insert-rectangle` macro to (try to) avoid possible
manual errors. The docs were edited the same way.

Right now the only client side info we have is whether debug is enabled, but we
expect more in the future.
We also preemptively prepare for the possibility of multiple errors when
gathering both daemon and client info.
